Chii chinonzi tensile simba rebasalt mineral fiber?
The tensile simba re basalt mineral fibersinyaya inoda kuongororwa kubva mumaonero akawanda. Kutanga, zvakakosha kujekesa kuti kusimba kwesimba kunoreva iyo yakanyanya tensile kusagadzikana chinhu chinogona kumira pamberi pekutyoka. For Basalt Fibers, kukosha uku kunowanzova pakati2000 MPa uye 4800 MPa. Iko kukosha chaiko kunopesvedzerwa nezvinhu zvakaita sekuumbwa kwezvinhu, maitiro ekugadzira, uye fiber dhayamita.
Sei uchidaro basalt fibersvane simba rakakwirira kudaro? Izvi zvine hukama zvakanyanya neiyo microstructure yavo. Basalt pachayo idombo rinoputika rine zvinhu zvikuru zvinosanganisira silicon dioxide, aluminium oxide, uye iron oxide. Mushure mekunyunguduka kwepamusoro-tembiricha, zvikamu izvi zvinoumba chimiro chinoenderera chetatu-dimensional network, iyo inopa iyo fiber yakanyanya kusimba. Kukurumidza kutonhora panguva ye Fiber Manufacturing hurongwa hunoita kuti mamorekuru aite deser, achiwedzera kusimudzira ma mechanic properties.
Izvo chaizvo zvinhu zvinokanganisa simba rekusimba zvinogona kutariswa kubva pane zvinotevera zvinhu:
-
Raw Material Kuumbwa: Kuumbwa kwebasalt ore kubva kwakasiyana kwakasiyana kunosiyana. Kazhinji, mbishi zvinhu zvine silicon dioxide zviri pakati pe46% ne52% zvinogadzira fiber dzine simba riri nani. Iyo yakawandisa yakakwira iron oxide yemukati inogona kutungamira mukudzikira kwesimba.
-
Maitiro ekugadzira: Tembiricha yekunyunguduka inonyatso kudzorwa pa1400-1500 ° C. Kana tembiricha yakanyanya kuderera, iyo melt viscosity ichave yakakwirira, zvichiita kuti kudhirowa kuve kwakaoma; kana yakanyanya kukwirisa, inogona kukonzera kuputika kwechikamu. Iyo yekudhirowa kumhanya zvakare yakakosha parameter; kana yakakurumidza, iyo fiber dhayamita ichave isina kuenzana.
-
Fiber Diameter: Basalt fibers ine dhayamita yakajairwa ye9-13 microns ine yakakurumbira tensile simba kuita. Kunyangwe ne theoretically akatetepa faibha aine simba repamusoro, anowanzo kanganisa mukugadzirwa chaiko.
-
Surface Treatment: Zvimwe zvigadzirwa zvinobatwa nepamusoro pekuvhara, izvo zvose zvinodzivirira fiber uye zvinogona kuva nemigumisiro pakusimba kwayo.
Mumashandisirwo anoshanda, maitiro ekusarudza akakodzera basalt fiber? Izvi zvinoda kugadziriswa zvichienderana nekushandiswa kwakananga. Kune zvikumbiro zvinoda simba rakawanda, senge zvimiro zvekusimbisa zvinhu, zvinokurudzirwa kusarudza zvigadzirwa zvine simba rezita pamusoro pe4000 MPa. Nezvezvinangwa zvakajairwa, senge zvinhu zvekudzivirira, simba rinodiwa rinogona kudzikiswa zvakakodzera. Izvo zvakakosha kuti uzive kuti murabhoritari bvunzo data inogona kusiyana nekuita munzvimbo chaidzo dzekushandisa. Zvinhu zvakadai sekushisa, humidity, uye kureba kwenguva refu zvinogona kukanganisa fiber kuita.
Nezve kuenzanisa kwe basalt fiber simba nemamwe mafiber, mashoma akajairwa data mapoinzi anogona kushandiswa kunongedzera: simba rekusimba reyakajairwa E-girazi faibha rinenge 3000 MPa, S-girazi faibha inogona kusvika 4500 MPa, uye kabhoni faibha iri pakati pe3000-7000 MPa. Kubva pakuona uku, simba rebasalt fiber riri pakati-kusvika-pamusoro. Nekudaro, mabhenefiti ayo ari mumutengo wakaderera wezvinhu uye zvirinani kutonhora kwepamusoro uye kugadzikana kwemakemikari.
Panyaya yekutonga kwemhando, iyo single-fiber tensile bvunzo nzira iri kushandiswa kuona simba. Panguva yekuyedzwa, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune muenzaniso wekugadzirira maitiro kudzivirira kuunzwa kwehurema nekuda kwezvinhu zvevanhu. Miyero yeindasitiri kazhinji inoda kuyedzwa angangoita makumi mashanu mafiber uye kutora avhareji kukosha semhedzisiro yekupedzisira. Sezvo paine imwe discreteness musimba refiber, iyi nhamba yebvunzo inogona kuve nechokwadi chekuvimbika kweiyo data.
Nezvemafambiro ebudiriro mune ramangwana, vaongorori vari kuyedza kuwedzera kusimba kwebasalt fibers kuburikidza nenzira dzakadai senanomodification uye composite spinning. Semuenzaniso, kuwedzera huwandu hudiki hwezvinhu zvakakosha kune zvigadzirwa zvinogona kukwirisa zvivakwa zvekunyunguduka; kushandisa electromagnetic munda-inobatsirwa kudhirowa tekinoroji inogona kuvandudza kufanana kweiyo fiber chimiro. Kunyangwe aya maitiro matsva achiri muchikamu cherabhoritari, anoratidza tarisiro yakanaka yekushandisa.
Kuchengetwa kwesimba rekusimba zvakare kunetseka kune vashandisi. Experimental data inoratidza kuti munzvimbo yakaoma pane tembiricha yekamuri, iyo simba rekuchengetedza mwero we high-quality basalt fibers inogona kuramba ichisvika pamusoro pe90% mushure memakore gumi. Nekudaro, munzvimbo dzepamusoro-tembiricha kana dzakaora, kukosha uku kuchaderera. Naizvozvo, mumashandisirwo einjiniya chaiwo, matanho akakodzera ekudzivirira anofanirwa kusarudzwa zvichienderana nemamiriro ekunze.
Pakupedzisira, inoda kuyeuchidzwa kuti kunyange zvazvo basalt fiber ine simba rakanyanya kusimba, iyo interfacial bonding performance inodawo kutariswa mune chaiyo zvigadzirwa. Semuenzaniso, mukongiri yekusimbisa zvikumbiro, kusimba kwekubatanidza pakati pefiber uye matrix kunowanzo kukosha kupfuura kusimba kwefiber pachayo. Izvi zvinoda kuvandudzwa kuburikidza nekurapa kwepamusoro kana kuwedzera kwekubatanidza maajenti.
